Easymirrors help?

I'm having trouble implementing easy mirrors, specifically in declaring a new mirror - I'm confused what the parameter 'center' is.

Code: ags

struct Mirrors2
{
 
  //tells the module that character "c" can be used as a mirror reflection.
  //Call this function at least once (i.e. give the module at least one character)
  //otherwise it can't work!
  //You should call this function as many times as there are mirrors in the room
  // that has the most mirrors.
  //For example if there are two mirrors in a room, and if that is the room
  //of your game that has the most mirrors, then call this function twice.
  //(with two different characters!).
  import static void AddMirrorChar(Character* c); 
  
  //Declares a new mirror in the current room. The player MUST be in that room when NewMirror is called!
  // This must be done only ONCE in the entire game (in "first time enters room")
  // The mirror starts disabled. It has to be enabled (using script) afterwards to be visible.
  //
  // 'mirror' is the object containing the sprite used as the mask.
  // 'center' is a marker. The center of its sprite (width/2, height/2) should be where the player would stand (his feet coordinates) if he was glued to the mirror ;)
  // 'symetry' is one of the symetries in the enum above
  // 'x_offset' and 'y_offset' allow to shit the reflection by a constant number of pixels
  // 'opacity' must be in 0.0, 1.0. Note: if the mirror's opcaity is 1.0 then it's fully opaque, therefore there's NO reflection!
  // 'distance_attenuation' (recommended value '60.0'): if the player stands 0 pixels away from the mirror, his reflection will appear fully opaque. If he's standing 'distance_attenuation' pixels away from the mirror (or more), his reflection will be fully transparent
  import static void NewMirror( Object* mask,  //set to null if no mask
                                Object* center, 
                                Region* reg,   //set to null if mirror always on
                                Mirrors_Symmetries symmetry,  
                                float opacity,  
                                float distance_attenuation,  
                                int x_offset=0,  
                                int y_offset=0);

  //Tells the module that this mirror should use an entirely
  //different character altogether as the reflection, instead of computing 
  //the reflection.
  //That character should use Views that have the same number of loops and frames
  //as the player character.
  import static void SetSubstituteCharacter(Object* mask,  Character* c);
  
  //To modify the offset you've set in NewMirror
  import static void SetOffset(Object* mask, int x_offset,  int y_offset);
  
  //To modify the opacity you've set in NewMirror
  import static void SetOpacity(Object* mask, float opacity);
  
  //That doesn't delete the mirrors in memory (which is done automaticaly). It just disables them so that they're not rendered
  import static void DisableAllMirrors();
  
  //Enables all mirrors in THIS room if they've been previously declared with 'NewMirror'
  import static void EnableAllMirrorsInRoom();
  
  //Enables one mirror selectively
  import static void EnableMirror (Object* mirror);

I'm confused what I should put for the center parameter.

My guess is that object is used to specify the coordinates used to position the mirror image. Draw a small cross hairs sprite (like 9x9 pixels or something like that) and put it on a new room object. Then move the object to the floor below the mirror.

[tilapisha]

Hmmm, I did that, and still nothing.

"Still nothing"?
As in, nothing mirrory happens in-game?
Did you activate the mirror?

The mirror starts disabled. It has to be enabled (using script) afterwards to be visible.

AddMirrorChar -> use this on game_start, if your room with most mirrors has 1 mirror, call once, if your room with most mirrors has 2 mirrors, call twice ...
You pass a dummy character to this function (NOT cGoby), this dummy character is going to be moved by the module, mirroring the character being reflected

NewMirror -> You are using this correctly in room_FirstLoad

You can also do something like the below

Code: ags

bool mirrorsCreated = false;

function room_Load()
{

  //do this for each room that has mirrors
  if (!mirrorsCreated) {
  Mirrors2.AddMirrorChar(cDummy);
  Mirrors2.NewMirror(oMirrorMask, oLeftMirrorCenter, null, eSymmetryHoriz,  1.0,  50.0, 0, 10);
    mirrorsCreated = true;
  }

  Mirrors2.EnableAllMirrorsInRoom();  
}

Now there's a catch, this module is like super old and it has a scripting error, so I know it says you can make the region be null, but that is a lie

You actually have to make a region in your room, which is the area where the character can stand that will activate the mirror. If you use for instance region 2 you can then pass region[2] there.

the mask is more something like this, with a hole so the cDummy can walk through the mirror border



Finally, I don't understand why you are making the game using 16-bit colors, this causes all sorts of hard to use alpha values, I don't know how things work in 16-bit

16-bit games don't use alpha on sprites themselves (they are created fully opaque), but they still may use Transparency property on objects.

Will you explain this to me? The picture is a bit confusing, I made a mask that covered the whole room, and left the mirror transparent, but the character still can be seen on the walls!
